MEANS FOR PRODUCING THE OXYHYDROGEN BLOW-PIPE FLAME.

SPECIFICATION formingpart of Letters Patent No. 261,852, dated August '1, 1882. Application filed March 25, 1882. (No model.)

To all whom it may concern Be it known that I, FREDERIG E. IVES, a citizen of the United States, and aresident of Philadelphia, Pennsylvania, have invented an Improvement in the Means for Producing the Oxyhydrogen Blow-Pipe Flame, of which the following is a specification.

The object of my invention isto supply the hydrogen element in the oxyhydrogen blowpipe flame without the use of the troublesome and expensive hydrogen-generators, gas-bags, gasometers, cylinders, Vaporizers, and other apparatus commonly employed for the purpose; and this object I attain in the following manner:

A portion of the oxygen gas required to produce the blow-pipe flame, and which may be .supplied either direct from the retort or from a gas-bag, gasometer, or cylinder in the usual manner, 1 cause to pass through a tube or chamber containing a supply of ether or other suitable volatile inflammable liquid, in order that it may become wholly or partly saturated with the vapor. Instead of passing the gas in bubbles through the volatile inflammable liquid, I force it through a tube or chamber which has a filling of cotton or other suitable porous material saturated with the liquid. The objectof this arrangement is, first, to prevent any unsteadiness of the flame, and, second, to prevent any spilling ofthe liquid into the tubes in case the hydrocarbon-chamber is upset. The

oxygen should be forced through or against a sufficient quantity of the cotton filling to insure a proper degree of saturation with the va por.. This may be donein various ways. The

simplest way is to employ a metal tube about twelve inches-long and one or two inches in diameter, connected as shown in the figure. With this arrangement a proper degree of saturation is insured until the ether isalmostexhausted, provided that the filling is neither packed too loose nor too tight. From the chamber containing the inflammable liquid or vapor the mixture of gas and vapor is conducted to the blow-pipe, where it may be ignited, and the volume of flame regulated by stop-cock in the usual manner. In order to bring the flame to a focus, more oxygen gas which is not saturated with the inflammable vapor may be admitted to the blow-pipe in the usual manner.

Any of the well-known forms of oxyhydro-.

gen blowpipe may be used, and the flame may be employed either as a simple reduction-flame or in the production of the lime-light.

In the drawing, Arepresents the blow-pipe, B the chamber for inflammable liquid, and G the oxygen-supply tube.

I claim- 1. The combination, in oxy hydrogen blowpipe apparatus, of a chamber containinga. filling of cotton or other porous material with an oxygen-supply tube, all substantially as and for the purpose specified.

2. The means for producing the oxyhydrogen blow-pipe flame, consisting of a chamber containing a porous filling which is saturated with a volatile liquid hydrocarbon, and an oxygensupply, all substantially as described.

Intestimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
